The dimming control signal is equivalent to a command output by an existing dedicated remote controller to control the lighting or extinguishing of the LED line lamp or the adjustment of the light intensity.

  The sound analysis control unit 5 is mounted on the sealing lid unit 1, and can acquire ambient sounds with a microphone 5 a such as a capacitor microphone, for example. Then, the sound analysis control unit 5 analyzes the collected sound data, generates a dimming control signal (command) such as lighting or extinguishing or adjusting the light intensity based on the analysis result, The LED drive circuit unit 3 is supplied. The sound analysis control unit 5 may be equipped with an amplifier as needed, and after the sound data collected by the microphone is amplified, the sound data may be analyzed. Details of the sound analysis control unit 5 will be described later with reference to FIG.

  The sound output device 6 is a device capable of outputting sound, such as a mobile phone, a smartphone, or a tablet terminal, for example, and the user uses sound output by operating the sound output device 6. The dimming operation of the LED line lamp can be performed. In other words, the user can use the sound output device 6 as a remote controller for the LED line lamp.

  As the sound output device 6, for example, a device that generates a synthesized signal sound defined by DTMF (English: Dual-Tone Multi-Frequency) used in a mobile phone or a smartphone is used. Is possible. In addition, when a device that many users carry for other purposes, such as a mobile phone or a smartphone, is used as the sound output device 6, the user should use a remote controller dedicated to the LED line lamp. In addition, a device already used for other purposes can be used as a remote controller of the LED line lamp, which is preferable.

  DTMF transmits a total of 16 codes of numbers 0 to 9 and symbols *, #, A, B, C, and D as a synthesized signal sound in two voice frequency bands of low and high groups Is the method. Also called “tone signal” or “push signal”, the signal sound is in the human audible range. The standards are specified as conditions for pushbutton dial signals in ITU-T Recommendation Q.24, and in Japan, Annex Table No. 2 based on Article 12, Item 2 of the Ordinance of the Ministry of Internal Affairs and Communications Terminal Equipment.

  Here, the sealing lid portion 1, 1 ′ can rotate the outer cylinder portion 2 composed of the heat radiating portion 2 a and the diffusing portion 2 b by applying the technique described in Utility Model Registration No. 3176594, for example. It is preferable that it can be gripped as described above.

  In the illustrated LED line lamp, a blue light emitting element covered with a yellow phosphor is used as the LED element 4a mounted on the LED substrate 4, and the diffusing part 2b is provided with a diffusing agent, thereby providing the blue color. It is preferable that the white irradiation light from the diffusing portion 2b can be output by the color mixing action of yellow and yellow.

  In addition to the mobile phone or the smartphone, the sound output device 6 may be, for example, a stationary phone, a small device that can be carried by the user such as a handset, a tablet terminal, or a personal computer. It is also possible to use a device that outputs a predetermined sound according to a user command.

  Next, the configuration of the sound analysis control unit 5 will be described with reference to FIG.

  The sound analysis control unit 5 includes a microphone 5a, a sound analysis unit 5b, an external input unit 5c, a memory 5d, and a control unit 5e.

  The microphone 5a supplies the collected sound data to the sound analysis unit 5b. Needless to say, the sound data collected by the microphone 5a includes the sound generated from the sound output device 6 described with reference to FIG. The microphone 5a may incorporate an amplifier as necessary.

  The sound analysis unit 5b analyzes the sound data supplied from the microphone 5a. If the sound data is a sound generated from the sound output device 6, the analysis result is supplied to the control unit 5e.

  For example, when a device that generates a synthesized signal sound defined by DTMF, such as a mobile phone or a smartphone, is used as the sound output device 6, it is preferable to use a DTMF decoder as the sound analysis unit 5b. Specifically, as shown in FIG. 4, the synthesized signal sound defined by DTMF is composed of 16 kinds of codes including numbers from 0 to 9 and symbols of *, #, A, B, C, and D. Are assigned so as to correspond to the synthesized signal sounds of the two voice frequency bands of the low group and the high group, for example, “1” is represented by the synthesized sound of two voice signals of 697 Hz and 1209 Hz. The other codes are similarly represented by synthesized signal sounds of two voice frequency bands of a low group and a high group. When a DTMF decoder is used as the sound analysis unit 5b, the sound analysis unit 5b analyzes the sound data supplied from the microphone 5a, detects two sound frequency bands of a low group and a high group, and outputs a sound. It is detected whether the sound generated from the device 6 is a number from 0 to 9 or assigned to a symbol of * or #, and the result is supplied to the control unit 5e. be able to. As the DTMF decoder, for example, CM8870 manufactured by California Micro Devices, Inc. can be used.

  In addition to the DTMF decoder, it is needless to say that a sound analysis unit 5b having a sound analysis function of various algorithms can be used. For example, a programmable microcomputer may be used.

  The external input unit 5c receives external input of information to be recorded in the memory 5d and records it in the memory 5d. As information supplied from the external input unit 5c, for example, a program executed by the sound analysis unit 5b or the control unit 5d, or necessary for the sound analysis unit 5b or the control unit 5d to execute processing, for example, will be described later. There is information such as a command list. The user or the manufacturer can customize the dimming control performed by the sound analysis control unit 5 by recording desired information in the memory 5d via the external input unit 5c.

  In the dimming control executed by the sound analysis control unit 5, when the program is preliminarily incorporated in the control unit 5d and the memory 5d is not particularly required, or processing is performed using only information recorded in the memory 5d in advance. In other words, the external input unit 5c may be omitted if the user does not customize the type of sound source used for operation input or change of command assignment. .

  The memory 5d stores a program executed by the sound analysis unit 5b or the control unit 5d and information necessary for the sound analysis unit 5b or the control unit 5d to execute processing. For example, when a device that generates a synthesized signal sound defined by DTMF, such as a mobile phone or a smartphone, is used as the sound output device 6, the memory 5d includes, for example, * and as shown in FIG. It is possible to record a command list in which a command for dimming is assigned to a symbol of # and numbers from 0 to 9.

  Note that the commands described in the command list may be the same as, for example, commands output by a dedicated remote controller in the dimming control of the existing LED line lamp.

  For example, when the sound analysis unit 5b is configured by a programmable microcontroller or the like, a program executed by the sound analysis unit 5b recorded in the memory 5d through the external input unit 5c as necessary. Is updated, the analysis processing algorithm executed by the sound analysis unit 5b is changed, and the command list is rewritten to change the type of sound source used by the user for operation input and the corresponding command. It becomes possible.

  Hereinafter, the case where the apparatus which produces | generates the synthetic | combination signal sound defined by DTMF, such as a mobile phone or a smart phone, is used as the sound output apparatus 6 as an example.

  The control unit 5e generates a dimming control signal to be supplied to the LED drive circuit unit 3 based on the analysis result of the sound data supplied from the sound analysis unit 5b and the information recorded in the memory 5d. This is supplied to the drive circuit unit 3. For example, a microcontroller or the like can be used as the control unit 5e. For example, if the analysis result of the sound data supplied from the sound analysis unit 5b is one of numbers from 0 to 9, or *, #, for example, the control unit 5e stores the memory 5d. The dimming control signal of the corresponding command is supplied to the LED drive circuit unit 3 with reference to the command list recorded in

  Specifically, for example, a microcontroller such as PIC16F1823 manufactured by Microchip Technology can be used as the control unit 5e. When the CM 8870 is used as the sound analysis unit 5b, the control unit 5e is supplied from the CM 8870. The dimming control of the LED element can be performed by performing PWM (Pulse Width Modulation pulse width modulation) control based on the 4-bit signal.

  It should be noted that the commands associated with the symbols * and # in the command list and the numbers 0 to 9 are used for dimming control of an existing LED line lamp that does not have the sound analysis processing unit 5. The same command as that output from the controller may be used. In this case, a control device corresponding to the sound analysis processing unit 5 is attached to the existing LED line lamp, and the dimming control signal output from the control unit 5e is transmitted to the LED drive circuit in the same manner as the command output from the dedicated remote controller. The sound output device 6 can be used as a remote controller for the LED line lamp simply by enabling supply to the unit 3 (that is, connecting the output of the control unit 5e and the input of the LED drive circuit unit 3). That is, the user can purchase only a control device corresponding to the sound analysis processing unit 5 and connect it to an existing LED line lamp without purchasing a new LED line lamp equipped with the sound analysis processing unit 5. A device that generates a synthesized signal sound defined by DTMF, such as a mobile phone or a smartphone, can be used as a remote controller.

  The control unit 5e may generate an articulation signal based on the analysis result of the sound data for each sound supplied from the sound analysis unit 5b and supply it to the LED drive circuit unit 3, for example. After obtaining the analysis result of the sound data corresponding to any one of the numbers from 0 to 9 or *, # from the sound analysis unit 5b, 0 to 9 within a predetermined time. It is assumed that an articulation signal corresponding to a command is generated and supplied to the LED drive circuit unit 3 only when an analysis result of sound data corresponding to any of the numbers up to or * or # is not obtained. Also good.

  A device that generates a synthetic signal sound defined by DTMF, such as a mobile phone or a smartphone, is a number from 0 to 9 or *, # when receiving an operation input such as a normal call by a user. It is assumed that a sound corresponding to any one is generated a plurality of times within a predetermined time. Therefore, in order to distinguish the operation input for a normal call or the like in the sound output device 6 from the dimming control operation input of the LED line lamp, the control unit 5e is a number from 0 to 9, or *, #, After obtaining the analysis result of the sound data corresponding to any one of the sounds, the number corresponding to any number from 0 to 9 or *, # within a predetermined time It is preferable that the dimming control signal corresponding to the command is generated only when the data analysis result is not obtained, because malfunction can be prevented.

  Next, an illumination control process executed by the sound analysis processing unit 5 will be described with reference to the flowchart of FIG.

  In step S1, the sound analysis unit 5b determines whether sound data has been acquired based on information supplied from the microphone 5a. If it is determined in step S1 that sound data has not been acquired, the process in step S1 is repeated until it is determined that sound data has been acquired.

  If it is determined in step S1 that sound data has been acquired, in step S2, the sound analysis unit 5b analyzes the sound data supplied from the microphone 5a.

  In step S <b> 3, the sound analysis unit 5 b determines whether or not the analyzed sound data is a sound generated by a predetermined sound output device 6. For example, the sound analysis unit 5b may be configured such that the analyzed sound data is a number from 0 to 9 generated from a device that generates a synthesized signal sound defined by DTMF, such as a mobile phone or a smartphone, or * , #, It is determined whether the sound corresponds to one sound. If it is determined in step S3 that the analyzed sound data is not a sound generated by the predetermined sound output device 6, the process returns to step S1 and the subsequent processes are repeated.

  If it is determined in step S3 that the analyzed sound data is a sound generated by the predetermined sound output device 6, the sound analysis unit 5b supplies the analysis result to the control unit 5e in step S4. Based on the analysis result of the sound data, the control unit 5e refers to the memory 5d as necessary, and extracts a command corresponding to the sound generated by the predetermined sound output device 6.

  In step S5, the sound analysis unit 5b determines whether other sound data has been acquired within a predetermined time based on the information supplied from the microphone 5a. Here, the predetermined time corresponds to a time required for a device used as the sound output device 6 such as a mobile phone or a smartphone to continuously perform operation input in a call or operation of various applications, for example. It is determined experimentally and empirically in consideration of the time to perform. If it is determined in step S5 that no other sound data has been acquired within a predetermined time, the process proceeds to step S8 described later.

  If it is determined in step S5 that other sound data has been acquired within a predetermined time, the sound analysis unit 5b analyzes the sound data supplied from the microphone 5a in step S6.

  In step S <b> 7, the sound analysis unit 5 b determines whether or not the analyzed sound data is a sound generated by a predetermined sound output device 6. When it is determined in step S7 that the sound is generated by the predetermined sound output device 6, a call or operation of various applications is performed on the device used as the sound output device 6, such as a mobile phone or a smartphone. Since it is estimated that the process is being performed, the process returns to step S1, and the subsequent processes are repeated.

  If it is determined in step S5 that no other sound data has been acquired within a predetermined time, or if it is determined in step S7 that the sound is not generated by the predetermined sound output device 6, then in step S8 The control unit 5e generates a dimming control signal corresponding to the command extracted in step S4, and outputs the dimming control signal to the LED drive circuit unit 3, and the process ends.

  By such processing, the user can command the dimming of the LED line lamp using the sound output device 6 that is not a dedicated remote controller and can output a predetermined sound.

  In the process described with reference to the flowchart of FIG. 6, the control unit 5e has been described as extracting a command corresponding to one sound supplied from the sound analysis unit 5b and generating a dimming control signal. For example, the control unit 5e may generate a dimming control signal based on a combination of a plurality of sounds.

  For a combination of a plurality of sounds, a device that generates a synthesized signal sound defined by DTMF, such as a mobile phone or a smart phone, for example, uses a combination that is considered not to be continuously input in a call or operation of various applications. It is preferable to do so. For example, the control unit 5e can detect any number from 0 to 9 or * or # within a predetermined time after “#-#” is detected by the analysis processing of the sound analysis unit 5b. Only when an analysis result of sound data corresponding to is obtained, a dimming control signal corresponding to the command may be generated with reference to the command list and output to the LED drive circuit unit 3.

  In addition, when a device that generates a synthetic signal sound defined by DTMF, such as a mobile phone or a smartphone, is used as the sound output device 6 and a DTMF decoder is used as the sound analysis unit 5b, many users may use it. A portable device can be used as a remote controller for the LED line lamp, eliminating the need to purchase a dedicated remote controller.

  In addition, if a device that is always carried by many users can be used as a remote controller for the LED line lamp, the user can perform dimming operations frequently as necessary. Connected and preferred.

  In addition, by recording a new program in the memory 5d using the external input unit 5c, the sound analysis process that can be executed by the sound analysis unit 5b is customized, and the sound output device 6 can be a mobile phone or a smartphone. Needless to say, it is possible to use devices other than the device that generates the synthesized signal sound defined by DTMF.

  In addition, by inputting data via the external input unit 5c, information such as a command list recorded in the memory 5d can be rewritten.

  As long as at least the microphone 5a is provided outside the sealing lid part 1, the sound analysis control part 5 may be mounted inside the outer cylinder part 2, for example, The LED drive circuit unit 3 may be configured on the same substrate.

  The above-described technology can be applied as hardware to, for example, a lighting device such as an LED line lamp or a control device that controls dimming of a lighting device such as an LED line lamp.
